How do scientists detect dark matter
WebSep 9, 2015 · It’s full of dark energy and dark matter, theoretical substances that scientists can’t detect but which we know must exist based on otherwise unexplainable phenomena—phenomena like the expansion of the universe. Scientists first discovered that the universe is expanding in 1998, using the Hubble Space Telescope. WebMost stellar black holes, however, are very difficult to detect. Judging from the number of stars large enough to produce such black holes, however, scientists estimate that there …
